2. 进入chroot环境config
[root@linux qt-everywhere-opensource-src-4.7.2]# time ./configure -prefix-install -release -opensource -shared -fast -no-largefile -no-qt3support -no-webkit -no-javascript-jit -no-scripttools -platform linux-g++ -no-openssl -nomake tools -nomake examples -nomake demos -nomake docs -continue -silent -no-nis -no-cups -glib -no-exceptions根据提示输入yes

Qt is now configured for building. Just run 'gmake'.
Once everything is built, you must run 'gmake install'.
Qt will be installed into /usr/local/Trolltech/Qt-4.7.2
To reconfigure, run 'gmake confclean' and 'configure'.

3. 编译
在编译前，先查看一下chroot环境的gcc版本吧
[root@linux qt-everywhere-opensource-src-4.7.2]# g++ -v
Using built-in specs.

5. 卸载
如果需要卸载Qt可以在原编译环境使用如下命令卸载：
[root@linux qt-everywhere-opensource-src-4.7.2]# gmake uninstall
6. 备份已编译好的目录
由于编译时间较长，即使以后卸载也要用到编译环境，所以最好还是备份一下编译环境。
tar jcf qt-everywhere-opensource-src-4.7.2.tar.bz2 ./qt-everywhere-opensource-src-4.7.2/
